i'd want a gundam series so it would be mecha, romance, seriousness but with some funny parts.
there would be lots of fighting but it would focus on the romance more then other gundam shows like gundam seed. still more fighting but with more romance!

but for another i would include all Fantasy, serious characters along with some funny one but not too over the top! romance, some sort of science fiction and mecha but not too much and adventure!
